Predator Ambush

Whenever a nontoken creature enters the battlefield under an opponents control, you may
reveal the top card of your library. If its a
dinosaur creature card, you may put that
creature onto the battlefield under your control.
If a creature was put onto the battlefield this way,
that creature fights your opponents creature that entered the battlefield this turn. Otherwise, you
may put that card on the bottom of your library.
